... The jets can also be produced in smaller scale by binary stellar systems. ... Some 200 -- 250 X-ray binaries, systems in which a neutron star or black hole is accreting material from a companion star, are known. Approximately 20% of these sources have been detected at radio wavelengths, and in several cases high resolution radio observations have resolved this emission into jet-like structures, sometimes with components moving at relativistic velocities. ... It is variable radio source. ...

This is the homepage of Andrew Fruchter, an astronomer on the staff of the Space Telescope Science Institute . ... Here you can look at an HST images of the optical counterparts of gamma-ray bursts and their host galaxies. ... Therefore, substantial information on the fine scale structure of objects can be obtained by offsetting the pointing of the telescope between exposures and then combining these "dithered" exposures into a single image. ...

Bursts, Pulses and Flickering: Wide-Field Monitoring of the Dynamic Radio Sky June 12-15 2007, Kerastari, Greece First announcement: Exotic and transient astrophysical phenomena reveal the violent and capricious nature of the universe. ... Radio telescopes have a tradition of providing high angular resolution in narrow fields or large fields of view with limited time resolution. A notable exception to this approach led to the discovery of pulsars thirty years ago. ...

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...

We cannot observe the way the distant universe accelerates cosmic rays or produces energetic photons, but acceleration processes also occur on our Sun , though on a much more moderate scale. ... That is why such events are often missed by cosmic ray detectors near the equator, where the lowest energies are excluded by the Earth's magnetic field. The best detectors for observing solar particles are therefore those sensitive to the lowest energies of the cosmic radiation. ...
